with the great help of this forum, I now successfully installed Win7 beside my Linux partition. Since I haven't used Windows in a whole while, I have to get used to how it behaves again.
My setup - as far as it concerns my Win installation - includes a SSD for the system and apps, as well as a large internal HDD for data storage. I was creating symlinks from the folders on my HDD to "My Documents", which work fine for direct usage. This also includes e.g. a symlink to the folder "Downloads", which is named exactly like that. It happens though, that if - for example - in my web browser (no matter which one), I click on a file to download it, Windows automatically creates a new directory, also in "My Documents", ignoring the existent symlink with the same name. This obviously defeats the whole purpose of the symlink.
Is there any way to prevent Windows from doing so? It seems that it doesn't make a difference whether I created the symlink via drag & drop or via cmd.
